FREDERICK; naar, or nanvrroan, conn. MENTS, To UNnnnWoon cone-orina Application filed 3E., 19M,

To all whom it may concern:

, Be it known that I, FREDERICK A. HART, a citizen ofl the United States, residing in Hartford, fin the county of Hartford 'and State of Connecticut, have in'vented certain `new and useful improvements in Combined Type-Writing and Computing Machines, of which the following is a specification. 1

This invention relates generally 'to that class of combined typewriting and adeline" machines in Which computing devices are set up by the numeral keys of the typewriter, and subsequently rotation is effected of the computing Wheels, each to an 'extent determined by the setting of the computing deyices by the numeral keys. rl`he carriage of specification of :i

. the typewriter isconnected to the computing;

mechanism in a manner to determine the de nomination of the computing device which is set by any key. A machine of this generai description is illustrated in my pending application No. 466,836, iiled December i0,

I One of the principal objects of the present invention is to provide simple and eflicient means for causing the general computing` operator to be actuated automatically, upon the Writing of any figure in the units place ina column, or in other Words, upon the setting up of a computing'device in the units place in the computing mechanism'.

In the preferred form of the invention, employ a constantly running motor, as t forth inamy pending application No. 396,i51i, filed December 9, 1910; and 'this motor, Whenever any key is operated to Write in the units place in a column, is caused to be cen-,

nected up to the general operator or the corn puting machine to reciprocate the saine, and

thereby eiect the desired setting oi' the coni- Aputingr Wheels. Said operator is shown in -said applications as of a reciprocatingtype, and a rotatable member is connected thereto by a crank, so that one rotation of saidv memberl will effect a complete reciprocation of the general operator.l rllhis rotatable member is'cgnnectible by a clutch to seid constantly running motor. rlie clutch is normally open. A connectionl ergbends from the key-controlled mechanism of the typewriting machine to said clutch, to eect the closing of the same automatically at the desired point in the line otwritingw Preferably the clutch tends normally to set forth inmy said applica illustrate in the inse, but it provided with restraining deviav h' holds it open; a. d in order to 4restraining device, i preferably prov de a power-driven releaser, which, however, is normally disconnected from icestraining device, but* the eperation 6o the typewvriting machine at the required point, is automatically connected to restraining device to release it and permit 'the clutchvto close= "Upon the carri o? the typewriter., there is mounted a. wip-tr, cam or t n' ne, step' of arriage, Whenever com" is begging7 operates eis whereby det `lined denomn the computing device te b pression ci a tfpewrite. tappet is caused also, acto ent in'iprcyeinents, to er a ary jack, which. in turn neces between. a constantly r'bratin said ciutch-resrainin clutch and perini to close, the carriage adi` ees (upon the type ire f employed to Write place) s superninnerary closing or said clutch, and hen Il, operator is actuated and Wheels rotated accordingly.

n is such, errer a comprit device is set y a the units piace in any of said groupa general operator will be a utomatically rccip rocated, and the computi wheeis in that Q nieuwe group turned accordingly; the wheels in the other groups being undisturbed. in this way, vertical adding may be done in each of two or more columns written upon the work Sheet; each group of computing mechanism being provided with a supernui'nerary jack for closing said clutch, and each of said supernumerary jacks being operable only by the cani or tappet which controls the jacks in the same group. .Provision is also made for silencing any ofthe supernumerary jacks, thus permitting various kinds of computation to be effected.

Other features and advantages will hereinafter appear. Y

In the accompanying drawings, Figure 1 is av part-sectional side elevation of an Underwood typewriterl combined with a computing machine of the Hanson type, and showing the present improvementsapplied thereto; the parts being` in normal positions, and certain devices being omitted for the sake of clearness. Fig. 2 is a sectional eievation showing particularly the connections for closing the clutch between the constantly running motor and the general operator of the computing mechanism; said clutch being shown open. Fig. 2A is a sectional view to illustrate the details of the clutch mechanism; the clutch being open.

Fig.

is a plan View of the rear portion of the typewriter carriage, and also showing vthree groups of jacks forming portions of the three groups of computing mechanism. Fig. 7 is a plan of a set of jacks, showing particularly the means for silencing the supernumerary jack when required. Fig. 8 is a sectional elevation of a supernumerary jack, showing it in normal position. Fig. 9 is .i perspective view of a button having an eccentric on which a supernumerary jack is pivoted, and whereby the latter may be swung un to silence it whenrequired. Fig. 10 is a View similar to Fig. 8, but showing the supernumerary jack as silenced.

Acontinuously running electric or other motor 1 is provided with a `main shaft 2,. the latter connected to a shaft 3 by means on said hub; another friction disk 7 being confined between disks 5 and 6. An arm 8 fast on shaft 3 is bent over at 9 to be engaged and driven by a lug 10 on disk 6. A compression spring 11 is coiled around the hub d, and adjusted by a nut 12 to determine how much of a load the clutch will carry without slipping.

ri rack '13, forming part of a rock frame, is movable forwardly and backwardly in the base of the adding machine, and performs the final portion of the computing operation. This rack frame is reciprocated intermittently by the constantly rotating shaft 3, by means of a clutch mechanism; said rack frame being connected to a crank shaft to,

be driven thereby, and the crank shaft being connected by a worm gearing to said shaft 3, as will presently be set forth.

Upon the rack rame is secured a yoke or carrier 111, in engagement'with `which is the upper end of an arm 15, provided on a cross head 1G, which moves forwardly and backwardly, or from left to right at Fig. 1, so as to reciprocate said rack frame 13; said cross head heilig carried on a horizontal slide 17, lwhich works in bearings 18 on a casing 19. This slide is reciprocated by means of a crank. 23, fixed ona horizontal shaft 24; said crank carrying a slide block 26, working in a groove 27 in the cross head. Loose on shaft 24 is a worm gear 30, meshing with a worm 31, the latter fixed on shaft 3, so that the worm wheel 30 is constantly rotating. The wormwheel 30 is connectible to shaft ,24: to turn the same whenever it is necessary-to reciprocate the' matically disconnected from the shaft 24,

and the latter cornes to a stop, while the motor'l continues to rotate.

Fixed to shaft 24: is a cup member 32 of a clutch; and fixed to the hub of worm gear 30 is a collar 33. Running on this collar and adapted to engage the inside, of a cylindrical face of the clutch c up 32, is a gripping ball or roll 34; said roll" occupying a pocket 35b in the clutch cup, and roll ing on an inclined ioor 35 thereof, so that relative movement of the clutch cup and collar 33 in one direction will cause said members to be clutched together by the roll, while relative movement in the op- A35 by means of an annular disk or ring 36,

which-rides loosely on the collar 33 within cup 32, and which is cut away at one place to-receive the roll 34, so as to engage the roll on both sides thereof. Rotation of ring non No. 596,451.

` .close land open.

antennas 36, therefore, shifts the roll.7 Against said ring 36 bears one end of a compression spring -lock together the 'clutch cup with the bearing collar to cause shaft 24 to rotate with gear 30. lnlother words, said spring tends normally to close the clutch. Normally, however, said ring 36 is restrained from causingy the roll to bind; or in other words, said ring is normally held in clutch-releasing position. For this purpose, there is provided a trip pin or latch 40, normally in engagement with a lug 41 Vprovided upon releasing ring 36, said lug projecting through an opening .in the clutch cup. 1iWhen shaft-24 is to be clutched to the gear 30, the latch 40 is raised to release lug 41, whereupon spring 3S throws ring 36, together with roll 34, thus locking the clutch cup and the shaft to the rotating worm gear 30. The pin 40 is automatically dropped again into the path of lug 41, so that at the completion of a single rotation of the shaft 24, the latter' is again unclutched from the worm gear 30.

The rack frame 13 is caused to reciprocat after the numeral keys of the typewriter have been operated to set up a number. This rack frame operates to turn the computing wheels tol different extents, depend-- ing upon the key operated. Itis necessary, therefore, in some cases, for the described clutch to operate after each number is lwritten on the typewriter; and while the present improvement relates particularly to means for securin0r such operation automatically, or without attention on the part of the operator, still 1 will first describe means whereby the operator may depress a special key to operate said clutch, and cause the reciprocation of the rack frame; this mechanism being substantially shown in my said applica- 42, and is mounted on a stem 43, pivoted at its lower end to a lever 44, fulcrumed at 45 upon the machine frame. Said lever 44, in turn, depresses a cross lever 46, which is pivoted at 47 to the framework, and at its otherend engages a notch 43 formed in the top of the trip pin or latch 40, so as to cause or control the up and down movement of said latch, whereby the clutch is caused to The lever 46 is provided with an adjustable end or arm 50, upon which the key lever 44 bears; this part 50 being adjustable by screws 52, thereby securing accuracy of' adjustment and movement of the clutch-controlling mechanism.

Depression of the key 42 carries down the Said key is designated ask I lever 44, the latter rocks the lever 46 about its fulcrum 47, the other end of the lever 46.

lifting the latch 40 away from the clutch lug 41. The operator immediately releases the key 42, which is returned to normal position by a spring 54. The movement of the key is limited by a pin 55 within a slot 56iin the key stem. spring 57.

The typewriter includes the usual set lof type-operating keys, including alphabet keys and also including numeral keys 88 mounted on levers 882L and connected by bell cranks 89 to type bars 90, which are thrown back against a platen 91 mounted'on a carriage 92. The carriage is power-driven, as usual,

and has a rack 97 meshing with a pinion 86,

The lever '46 has a returningy connected with an escapement wheel 85, lthe latter controlled by dogs 84, 'operated by universal bar 83, which is actuated by th'e ltype bars, so that whenever any vtype key is,

actuated, the carriage 92 is caused to feed a letter space. v

Fastened at the back of the carriage 92, are brackets 93, carrying a rack 94, to receive adjustable cams or tappets 95. Whenever any tappet, during the travel of the carriage, passes beneath the set of jacks 96, it raises the forward ends of the jacks in succession, turning each on its pivot 97, and depressing its rear end to press down the corresponding one of a. 'set of wires 98.

These wires are connectedl at their lower ends to levers 99 on a fulcrum rod 100. Each lever 99 raises one of a set of linkages 101, each linkage having a pin 102 to lift the rear end of a rack 103, the forward end of which meshes with a pinion 104 'connected to a computing wheel 105. Each rack carries a set of index pins '106, and one of these is. depressed to set up or index said number by theoperated type key 88; each key hav` ing a stem 110, for this purpose, to depress a crank 112, fast to a shaft 113, which is connected to a linkage 114, to depress one of the pins 106 upon the lifted rack bar 103; there being one linkage 114 for each key, each linkage being in Aposition to depress a corre'- I spending pin 106 on whichever rack is lifted, as set forth in my pending applications.

After the keys S8 are manipulated to write a number, and the corresponding racks 103 accordingly elevated as the paper-carriage feeds along, and certain pins 106 thereon depressed, there must vbe caused a reciprocati on ofthe rack frame 13. This frame usually includes a pair of arms 115 connected by a transverse horizontal bar 116, which is in position to engage all the displaced pins 106, and to give corresponding forward endwise movements to their racks 103, thereby turning the computing wheels 105 accordingly; the return movements of Ythe racks not turning said wheels, however, be.

shown) between said wheels and their drive pinions 104. Pinions 116a meshing with racks 13, are also in mesh with segments 116b fixed on rock-shaft 116e. This computation movement lofthe rack frame or socalledl operator 13fis secured automatically, at the completion ofthe writing of a number, that' is, without the`necessity of depressing the key 42, and without the necessity of thev operator keeping/the matter in mind. For this'purpose, at the left-hand end of each group of jacks 96 is placed a supernumeraryl jack 117, connected by a wire 98 to a bell crank 123, pivoted on s'haft 100 at the left-hand end of the gang of levers 99. links 128 to arms 124, depending from a horizontal transverse rock shaft 125. The middle link 128 has-a forward extension 128A, carrying a p in 129, which at the movement ofany of the bell cranks 123, is thrust forwardly against a 'link 130, the latterpivoted near its upper. end on an arm 143, for

the'purpose.v of vibrating the-latter. This link 130 is normally idle,but is capable of swinging to position to form an interponent or movement-transmitter between said arm 143 and an arm 132, which latter is powerdrivenand constantly vibrates up and down, so that said arm 143 'is vibrated, together with rock shaft 144 on which it is fixed, and an arm 147 on said shaft 144 swings down to operate the lever 46, which it will be'remembered, lifts tlie clutch latch soV that the shaft 24 becomes clutched tothe gear 30, and hence the rack frame or operator 13 is caused to reciprocate.

The arm 132 is kept in'constant vibration by means of a follower 134, the' lower yend whereof is pressed by a spring 1'35 against a wheel 133, which is in the nature of a Astar wheel or cam wheel, consisting of a4 succession'of depressions and elevations. `This4 wheel 133 is fixed to the worm gear 3 0, and hence theA arm 132 is constantly vibrated up and down while the motor 1 is inv operation. The arm 132 is adjustably connected to 'the follower 134 by means'of a pivot 132A and adjusting screws 1321, as 'seen at Fig. 4.

It will be understood that when the pin 129 thrusts forward the interponent 130, the 'latter is swung .to position over the arm 132, as seen at Fig. .4, and the latter, when rising, thrusts up the Vinterponent 130,'and swings arms 143 and 147, and trips'the clutch, as already eXplainedysol that the -computing operation vis completed 'automatically as the paper carriage 92 of the typewriter completes the letter spacing operation which is occasioned by the lreturn to normalfposition of` the type-operating numeral key 88 which' was employed to write in the units place. l

At Fig. 6 are shown in-plan three groups of jacks 96 and three tappets 95, one for The bell cranks 123 are connected by' ofuse as he may desire.

each of 'said groups, as set fbrth in my said application No. 466,836; these tappets being independently adjustable along the rack bar 94 on said paper carriage 92. It will three columns are being written at the same time upon the work she'et.

` Provision is made for silencing any one or more of the jacks 117 at Fig. 6, as will be understoodiby reference to Figs. 7 to 10.

' 'Each jack is pivoted upon a pin 148, which is formed eccentrically upon a stub-shaft 149, which is journaled in the jack frame 150 in line at Fig. 7 with the pivot 97 of the' denomination jacks 96. Upon each stubshaft is provided a button 151, whereby the pivot 148 may be rotated from its normal depressed position at Fig'. 8 to its elevated position avt Fig. 10, the jacks 117 in theformer case being held down in working position, and inthe latter case b/eing lield up clear of the tappets 9 5, s'o that the actuation of the general operator 13 will not occur. The but tons are' independently movable, so that the operator may have such jacks 117 in or out Each stub-shaft 149 may be held in either of its Figs. 8 and 10 positions by means of a spring 152 and detent pin 153, the latter engaging a depression 154` in the stub-shaft.

Variations may b resorted to within the scope of the'inventins, and portions of the improvements may be usedjwithout others. Havingv thus described my invention, I claim: f c
